Definitions

  • This invention concerns lever key blanks and particularly lever key blanks for use in a key cutting machine, a plurality of lever key blanks, a stack of lever key blanks, and also a key cutting machine.
  • lever keys though it is often problematic to provide a stack of blanks, as the blanks in the stack will tend not to lie flat on each other, and the blanks in a stack will often end up, and especially at the upper end of the stack, being inclined relative to the blanks at the lower end of the stack.
  • the generally cylindrical profile of the shanks and collars of these key blanks also results in the blanks sliding past one another when stacked. This can prove problematic, with blanks becoming jammed for instance in a magazine, cartridge or elsewhere, and can lead to difficulties in handling the lever key blanks, and particularly mechanically.
  • Lever keys generally include a head, which is usually flat.
  • a shank which is usually cylindrical but may in some instances have a non-circular (e.g. polygonal) longitudinal cross section, extends from the head.
  • a cylindrical shank provides the advantage of a smooth rotational support surface whilst the key is turning in a lock, whereas a shank with for instance a rectangular longitudinal cross-section may catch in the lock whilst turning.
  • a cylindrical profile also results in a stronger shank and is therefore less prone to deformation.
  • a collar Spaced along the shank is usually a collar which is often cylindrical, but may be frusto conical, and of greater diameter than the remainder of the shank.
  • the collar serves to locate the lever key at a required depth in a lock.
  • a collar which extends around the whole (e.g. cylindrical) or majority of the longitudinal cross section of the shank provides a larger, and therefore more stable abutment surface.
  • a blade is usually provided beyond the collar, which blade is again generally flat and usually parallel to the head. The blade is cut so as to activate a particular lock.
  • US 2002/0134122 A1 discloses a cylinder-pushing type of lock device, which comprises a core cylinder mounted in a centre casing hole of a lock casing; the core cylinder has a cylindrical hole for receiving a plurality of tumbler disks, which are pushed in place with a main spring underneath.
  • the stacking formations may comprise a pair of parallel flat engagement surfaces. Stacking formations may be provided on the collar of the lever key blank.
  • the distance between the stacking formation engagement surfaces may be the same as the shank diameter of the lever key blank.
  • Figs. 11 and 12 show a third key blank 40.
  • the stacking formations are provided in the key blank head 42, in that the key blank head 42 is of increased thickness such that the thickness of the head 42 is equal to the other part of the key blank 40 of greatest thickness, which is the collar 44.
  • the collar 44 may also have flat parallel engagement faces, or could be provided with a conventional cylindrical profile.
  • the key blanks 40 form a stack of parallel blanks by virtue of the thickness and parallel sides of the head 42.
  • Figs. 13 to 17 show the heads respectively of third, fourth, fifth, sixth and seventh key blanks 46, 48, 50, 52, 54, where only part of the key blank head is of increased thickness but will provide the stacking effect as shown in Fig. 11 .
  • the key blank head 56 of the third blank 46 shown in Fig. 13 has a raised rim 58 of increased thickness.
  • the key blank head 60 shown in Fig. 14 of the fourth key blank 48 has raised portions 62 either side of the key blank head 60.
  • the key blank head 64 of the fifth key blank 50 shown in Fig. 15 has a raised portion 66 adjacent to the shank to provide the increased thickness.
  • the key blank head 68 of the sixth key blank 52 shown in Fig. 16 has a raised band 70 extending transversely across the head, which band 70 could for instance show the logo and/or name of the key blank maufacturer or supplier.
  • a raised rim 74 is shown around a conventional hole 76 provided in the key blank 72 head for mounting a key on a key ring or otherwise.
  • the distance between the blanks could be greater than the diameter of the shank.
  • stacking formations could be provided elsewhere on a lever key blank, such as along the shank. Providing the distance between the stacking formations the same as the shank diameter is though advantageous in readily providing a stack.
  • the weight of keys in the stack will urge them to a parallel alignment as shown for instance in Fig. 11 .
  • the shank may not be cylindrical, for example a shank with a pentagonal longitudinal cross section could be provided.
  • the collar of the lever key could extend around a part, the majority, or the whole of the longitudinal cross section of the shank.
